互联网研究机构分析Twitter用户在接触前和接触后的行为
Analyzing Twitter Users' Behavior Before and After Contact by the Internet Research Agency
摘要：
近年来，社交媒体平台被用来进行选举干预。特别是，俄罗斯支持的互联网研究机构（IRA）已被确定为2016年美国总统大选前在Twitter上传播错误信息的主要来源。这项研究的目的是了解一般Twitter用户在第一次接触IRA账户后的一年内是否改变了他们的行为。我们比较了联系用户的前后行为，以确定他们的平均推文计数，推文的情绪以及提到@realDonaldTrump或@HillaryClinton的推文的频率和情绪是否存在差异。我们的研究结果表明，在大多数这些指标中，用户总体上表现出统计上显著的行为变化，而那些参与IRA的用户通常表现出更大的行为变化。
英文摘要：
Social media platforms have been exploited to conduct election interference in recent years. In particular, the Russian-backed Internet Research Agency (IRA) has been identified as a key source of misinformation spread on Twitter prior to the 2016 U.S. presidential election. The goal of this research is to understand whether general Twitter users changed their behavior in the year following first contact from an IRA account. We compare the before and after behavior of contacted users to determine whether there were differences in their mean tweet count, the sentiment of their tweets, and the frequency and sentiment of tweets mentioning @realDonaldTrump or @HillaryClinton. Our results indicate that users overall exhibited statistically significant changes in behavior across most of these metrics, and that those users that engaged with the IRA generally showed greater changes in behavior.
